LAVA tablets not approved by SU

Thursday, May 30th, 2013

Over the past few days Lava, a company based in India, has been soliciting students of Stellenbosch University, trying to sell their tablets.

According to the company, Stellenbosch University approved the sale of their tablets to students. This is completely false. Stellenbosch University has no
knowledge of any correspondence or contract with Lava to sell their tablets.

As tempting as it may seem to buy a very cheap tablet from the company, please do not supply them with your personal or bank details when asked or conduct any business with them.

Your security and personal information is of the utmost importance to us. We will never give any personal information, including contact details of our students to ANY company for soliciation purposes.

If you have been contacted and have any information, please contact Ilse de Kock (idk@sun.ac.za).

Access control on SU and private devicesToegangsbeheer op US en privaattoerusting

Friday, April 26th, 2013

With choice and freedom, inevitably comes some guidelines, rules or policies. This is also the case with the university’s  approach to the usage of electronic equipment, such as laptops, phones and tablets in the near future.

Due to our ever changing technological landscape Information Technology recently saw the need to  compile a policy to act as a guide for the use of SU and private devices. (Read our previous article on BYOD.)

Then End-user equipment and media policy establishes rules for the appropriate use of end-user equipment and media in the Stellenbosch University environment in order to protect the confidentiality and the integrity of academic and institutional information and applications as well as the availability of services at the University. It specifies the University and individual user responsibilities for processing, managing, and securing academic and institutional information on University and privately owned equipment (devices) and media.

These guidelines apply to all staff, students and associates who access the University network and information that relates to University owned or privately owned end-user equipment that will be used to connect to, access and/or process academic and institutional information.

This week we’ll look at the measures that have to be taken when it comes to access control to devices.

Prior to initial use via a physical connection to the University internal network or related infrastructure, all end-user equipment (with the exception of devices that are used to connect via Virtual Private Network (VPN)) must be registered with University Information Technology (IT) Division.

The IT Organisation reserves the right to:

– Refuse, by physical and non-physical means, the ability to connect privately owned or non-sanctioned end-user equipment to the University Network. The IT Organisation will engage in such action if it feels such equipment is being, or may be, used in a way that puts the University’s systems, information or users at risk.

– Summarily ban the use of a privately owned end-user device at any time. The IT Organisation need not provide a reason for doing so, as protection of the University Network and information is of the highest priority.

– Physically disable communication ports (such as Universal Serial Bus (USB) ports, other ports that can connect to storage devices or media) on University-owned IT assets to limit physical and virtual access to University systems and information.

– Users who wish to connect privately owned or non-sanctioned end-user equipment to the University Network to gain access to University applications or information and/or the Internet must implement, for their devices and related infrastructure, appropriate and up-to-date:

* personal firewall;

* anti-virus software;

* anti-malware software;

* any other security measure deemed necessary by the IT Organisation;

* operating systems (e.g. Microsoft Windows, Android, Apple iOS, etc.) and operating system updates.

– Users must implement physical security practices to prevent the theft or loss of end-user equipment and media, especially mobile devices, and academic and institutional information, including:

– If it is absolutely necessary to leave a portable device unattended, it should be secured with a cable lock or similar security device,

– Ensure that portable devices are not visible when left in a vehicle. If portable devices are left unattended in a vehicle it is recommended that they be locked in the boot.

– Lock portable devices away when not in use.

– Portable end-user media or devices which contain confidential academic and institutional information must be protected by an access control mechanism (e.g. password, biometric, PIN code or pattern lock, etc.). If the latter is not possible, access to data files on these devices or media, must be protected by an access control mechanism. Devices that are unprotected by an access control mechanism may not hold confidential1 academic and institutional information.

Dis onvermydelik dat, saam met keuse en vryheid, daar ongelukkig ook riglyne, reёls en beleid moet wees. Dis ook die geval met die universiteit se benadering tot die gebruik van elektroniese toerusting, byvoorbeeld skootrekenaars, selfone en tablette, in die nabye toekoms.

As gevolg van die voortdurend veranderende tegnologiese omgewing het daar`n behoefte ontstaan om `n beleid saam te stel wat as gids dien vir die gebruik van US-en privaattoerusting. (Lees ons vorige artikel oor BYOD.)

Die eindgebruikertoerusting- en mediabeleid vestig die reёls vir die toepaslike gebruik van eindgebruiker toerusting en media in die Universiteit Stellenbosch-omgewing. Die doel daarvan is hoofsaaklik om die vertroulikheid en integriteit van akademiese en institusionele inligting en toepassings, sowel as die beskikbaarheid van dienste by die universiteit, te beskerm.

Hierdie riglyne is van toepassing op alle personeel, studente en belanghebbendes wat toegang tot die universiteit se netwerk en akademiese en institusionele inligting deur middel van US-toerusting of privaattoerusting.

Die week kyk ons na die vereistes wat gestel word rakende toegangsbeheer na die toestelle. 

Voordat toegang tot die interne Universiteitsnetwerk of verwante infrastruktuur deur middel van `n fisiese verbinding bewerkstellig kan word, moet alle eindgebruikertoerusting (met die uitsondering van toestelle wat gebruik word om aan die VPN (Virtual Private Network) te verbind), registreer word by Informasietegnologie. 

Informasietegnologie behou die reg om: 

– te weier (op `n fisiese of nie-fisiese wyse) dat privaattoerusting of nie-goedgekeurde eindgebruikertoerusting aan die US-netwerk verbind word. IT sal hierdie besluit neem indien daar bepaal word dat die toerusting in so `n mate gebruik word dat dit die universiteit se stelsels, informasie of gebruikers tot nadeel strek.

– privaattoerusting te enige tyd te verban. IT hoef nie `n rede te verskaf vir die aksie nie, aangesien die universiteit se netwerk en informasie die hoogste prioriteit dra.

– fisies kommunikasiepoorte (soos USB’s of ander poorte wat kan verbind aan stoortoestelle of media) op universiteitsbates se fisiese en virtuele toegang tot universiteitstelsels en informasie te beperk. 

Gebruikers wat privaattoerusting of nie-goedgekeurde toerusting wil gebruik om toegang via die us-netwerk te kry na toepassings of informasie, se toerusting moet op datum wees met die volgende sagteware en hardeware:

* persoonlike vuurmuur;

* anti-virus sagteware;

* anti-“malware” sagteware;

* enige ander sekuriteitsmaatreels wat vereis word deur IT;

* bedryfstelsels (byvoorbeeld, Microsoft Windows, Android, Apple iOS, ens.) en bedryfstelselopdaterings.

Daar word ook van gebruikers vereis om sekuriteitsmaatreels in plek te sit om te voorkom dat toerusting, veral mobiele toestelle, media en akademiese en institusionele inligting, verlore raak of gesteel word. Hierdie maatreels sluit die volgende in:

– draagbare toestelle, indien nie onder toesig, moet beveilig word met `n kabelslot of soortgelyke toestel, 

– maak seker dat draagbare toestelle nie sigbaar is wanneer dit in `n voertuig gelos word nie. Sluit dit eerder in die kattebak toe.

– sluit draagbare toestelle indien nie in gebruik nie,

– draagbare eindgebruikertoestelle wat vertroulike akademiese en institusionele inligting bevat moet beskerm word deur `n toegangsbeheermeganisme (byvoorbeeld `n wagwoord, biometrie, PIN-kode of patroonslot, ens.) Indien laasgenoemde nie moontlik is nie, moet toegang tot data leers of media op die toestelle, beskerm word deur `n toegangsbeheermeganisme. Toestelle wat nie beskerm word deur genoemde meganisme nie, mag onder geen omstandighede vertroulike akademiese of institusionele inligting bevat nie. 

 

 

ABSA phishing now also in Afrikaans!

Tuesday, March 19th, 2013

Just because an e-mail from a “bank” is sent to you and it is in perfect Afrikaans, don’t be fooled into thinking it is legitimate.

The following e-mail was sent to a number of South African addresses and is a very clever and convincing attempt to obtain users banking details and PIN codes. What is frightening about this mail is that it is written in near-perfect Afrikaans and would fool most people including myself – if I weren’t so paranoid.

Take a look at the following mail message. It looks very convincing but some spelling mistakes give it away but are not easily seen!

Subject: Absa Kredietkaart Rekening Staat -Fooi Afgetrek

absa-afrikaanse phishing

There is an attached .html file (a web page) which immediately should tell you that something is wrong.

Here is what the web page looks like:

absa-afrikaanse phishing2

On closer inspection of the webpage coding reveals that this is a phishing scam run by a syndicate whose servers are currently in Italy.

  • If you use this page to type in your Account number, PIN code and password, you will have given the criminals free and open access to your bank account (if you were with ABSA)
  • ABSA, or any bank, would never send you e-mail containing links and ask you to click on that link to verify ANY personal information, especially account numbers or PIN codes.
  • Embedded html pages would never be included because they can be easily compromised (like this one)
  • Don’t be fooled by alarming subjects like “Fooi Afgetrek”, “Security Upgrade”, “Illegal Access to your account” or if the mail is in Afrikaans!

Beware of SIM card swap fraudOppas vir SIM-kaart omruilbedrog

Friday, February 22nd, 2013

 

Although it is a known scam, when it hits one of your colleagues, it makes you aware that there are very real dangers out there. A SIM card swap fraud occurs when criminals obtain and utilise a replacement SIM card to acquire security messages and one-time passwords (OTP) sent to you by the bank. Using the OTP, criminals are able to change, add beneficiaries and transfer money out of your account using your personal information that they would have obtained through phishing. One of our colleagues lost R20 000 over the holidays and asked us to warn other staff as well:

How does a SIM swap scam work?

  • The SIM swap takes place after the fraudsters have received a your bank logon details as a result of the you responding to, for example, a Phishing e-mail. (this is why phishing e-mails are so dangerous and you should never ever respond or click on links contained in these phishing e-mails.)
  • Once the fraudsters have the your cell phone number and other personal information, the fraudster can pose as you, requesting a new SIM card from a cellular service provider.
  • The cellular service provider transfers the your SIM card identity to the new SIM card, cancelling your old SIM card in the process.
  • The result is that there is no signal on the old SIM card, which means the you cannot receive / make phone calls or send SMS messages. (This ought to be the first sign of something wrong, so if you get  “SIMCARD INVALID” error on your cell phone)
  • The SMS authorisation reference number, which is normally sent to the client, reaches the fraudster instead of you, the legitimate owner, and the fraudster is able to make once-off payments and create beneficiaries fraudulently

What should I do if I suspect an unlawful SIM swap?

  • If you fall prey to an unlawful SIM swap, or suspect that you have, contact your cellular service provider for assistance.
  • Also contact the internet banking helpdesk to request that your internet banking access be suspended with immediate effect. This will prevent fraudsters from gaining access and transacting on your accounts.

What can I do to prevent SIM swap fraud?

  • Protect your information – all your information.
  • Do not disclose your ID number on websites unless you have verified the legitimacy of the site. The bank already knows your ID number and will not require you to give it to us again.
  • Do not disclose your cell number on websites unless you have verified the legitimacy of the site. Phishing sites often request for information such as ID Number, email address and email address password, physical address, etc.
  • Always make sure that your contact details on Internet banking are valid and correct. You know when your details have changed, so when you are ready, you can update the information on Internet banking or at a local bank branch.

Dis `n bekende kuberstrik, maar as dit met een van jou kollegas gebeur, word dit skielik `n realiteit en groter moontlikheid dat dit ook met jou kan gebeur. SIM-kaart bedrog vind plaas as kuberkriminele `n SIM-kaart ruiling gebruik om jou sekuriteitsboodkappe en eenmalige wagwoorde, gestuur deur jou bank, te bekom. Deur die eenmalige wagwoord te gebruik, kan begunstigdes se detail verander word, nuwes byvoeg en fondse uit jou rekening oorgedra deur jou persoonlike inligting te gebruik. 

Gedurende die afgelope vakansie het een van ons Tygerberg-kollegas R20 000 op hierdie wyse verloor en versoek dat ons ander personeel ook  waarsku.

Hoe werk `n SIM-kaart omruiling?

  • `n SIM-kaart omruiling vind plaas nadat kuberskelm jou bank aantekeninligting geoes het, omdat jy op `n “phishing” e-pos reageer het. (Hierdie is een van die redes hoekom “phishing” e-posse so gevaarlik is en jy nooit daarop moet reageer of op die skakels in dié e-posse moet kliek nie.)  
  • Sodra die persoon jou selfoonnommer en ander persoonlike inligting in die hande gekry het, kan hy jou identiteit aanneem en `n nuwe SIM-kaart versoek van jou selfoonverskaffer. 
  • Die selfoonverskaffer dra jou SIM-kaart identiteit oor na die nuwe SIM-kaart en kanselleer die ou kaart. 
  • Geen sein word vanaf die ou SIM-kaart ontvang nie en geen SMS’e kan gestuur of oproepe kan gemaak word nie.  Hierdie is die eerste teken dat daar fout is, ook as jy die boodskap “SIMCARD INVALID” kry.
  • Die SMS-magtiging verwysingsnommer, wat normaalweg aan die klient gestuur word, bereik die kuberkraker ipv jou, die geldige eienaar, en hy kan eenmalige betalings maak en begunstigdes skep. 

Wat moet ek doen as ek `n onwettige SIM-omruiling vermoed? 

  • Indien jy die slagoffer is van `n onwettige SIM-omruiling of vermoed dat jy moontlik is, skakel dadelik jou selfoonverskaffer vir hulp.
  • Kontak jou internetbankdienste hulplyn en versoek dat internetdienstetoegang onmiddellik beëindig word. Dit sal voorkom dat die skuldiges toegang tot jou rekeninge verkry. 

Wat kan jy doen om SIM-kaartbedog te voorkom?

  • Beskerm jou informasie – al jou informasie.
  • Moet nooit jou ID-nommer verskaf tensy jy doodseker is van die geldigheid van `n webwerf nie. Die bank het reeds jou ID-nommer en sal dit nie weer vra nie. 
  • Moenie jou selfoonnommer verskaf op webwerwe tensy jy die egtheid van die webwerf geverifieer het nie. “Phishing” webwerwe versoek gewoonlik inligting soos `n ID-nommer, e-posadres en e-pos adres wagwoord.
  • Maak altyd seker dat jou kontakdetails op internetbankdienste geldig en korrek is. Wanneer jou inligting verander, dateer dit op by op internet bankdienste of by jou plaaslike bank.

Keep your cell phone secureHou jou selfoon veilig

Friday, February 22nd, 2013

These days your smartphone is just as powerful as your laptop or pc a few years back. You store more personal and work information on your device and it’s always connected to the internet.

It’s exactly this convenience that puts you as a smartphone user at risk. Cooltech, iAfrica’s tech section, has a few ideas to minimise risk and ensure your personal information stays, well, personal and safe from malware and cybercriminals and other security risks.

Set up a password

Your first line of defense is to simply set up a password on your phone. Most cellphone providers allow you to type in a pin number each time you switch on your phone or after a period on inactivity.

Install security software

Since smart phones are no longer just for storing phone numbers and sms’s, but also bankdetails, they’re also an easy and perfect target for cybercriminals.

Consider installing anti virus software to protect your device against malware. F-Secure, Norton and other large security software vendors each have their own version for the main smartphone platforms.

Activate the remote wipe function

The biggest risk is the the theft or loss of your device. Rather than worry about a stranger snooping through your information, activate the remore wipe function.

This function will allow you, by means of an internet connection, to delete your photos, business contacts and e-mails when you suspect you might not be able to recover your phone.

Some manufacturers like BlackBerry and Apple offer the remote wipe function and location applications for their latest devices, while third party applications are available for other platforms.

Download safe and approved applications

The temptation to download a free, unofficial application on your iPhone or Android instead of purchasing one through iStore, is big, but do you really want to take the risk and expose your phone to malware.  Rather stick legitimate sources where proper quality control is done and applications don’t come with added nasty surprises.

Backup your data

As we’ve already established, a substantial amount of your life is on your smart phone – e-mail, phone contacts, documents, photos and much more. Just as you back up your computer (hopefully!), do the same with your cell phone so you won’t lose everything if you lose your phone.  Many smartphones allow you to make a thorough backup from your device to your pc or at least sync the most important data and settings to an online service.  Many smartphones allow you to make a comprehensive backup of your device to a computer, or to sync your most critical data and settings to an online service.

Jou slimfoon is deesdae net so kragtig soos jou skoot- of tafelrekenaar van`n paar jaar gelede. Jy stoor ook meer kosbare persoonlike en werksinligting daarop en is feitlik altyd verbind aan die internet. Dit is egter ook juis hierdie gerieflikheid wat vereis dat jy net soveel sekuriteit toe pas op jou selfoon as wat jy op jou rekenaar sou gebruik.  

Cooltech, iAfrica se tegnologiese afdeling, het `n paar idees om seker te maak dat die inligting op jou foon veilig bewaar word van “malware”, kuberkriminele, toestelfoute en ander sekuriteitsrisikos.

Stel `n wagwoord op 

Die eenvoudigste en eerste stap is om doodeenvoudig `n wagwoord op jou foon te sit. Meeste slimfoonvervaardigers laat jou toe om `n pinnommer of wagwoord in te sleutel elke keer as jy jou toestel aansit of weer gebruik na `n tydperk van onbruik. 

Installeer sekuriteitsagteware

Aangesien slimfone nie meer net telefoonnommers en sms’e stoor nie, maar ook, onder andere, bankinligting, is hulle ook `n maklike en perfekte teiken vir kuberskelms. 

Oorweeg dit om antivirus-sagteware te installeer om jou toestel te beskerm teen “malware”. F-Secure, Norton, en ander groot sekuriteitsagteware-verskaffers bied elk hul eie weergawe vir die hoof slimfoon platforms. 

Aktiveer die afstanduitvee-funksie

Die grootste risiko vir jou as slimfoongebruiker is as jou toestel gesteel of verlore raak. Eerder as jou bekommer oor iemand wat deur jou belangrike inligting snuffel, aktiveer die uitveefunksie wat van `n afstand gedoen kan word. 

Hierdie funksie sal jou toelaat om jou fotos, besigheidskontakte en e-posse uit te vee met die hulp van enige internetverbinding as jou foon weg is en jy vermoed jy gaan dit nie weer terugkry nie. As jy nog nie jou foon wil opgee nie, kan sekere posisiebepalingsfunksies jou help om `n idee te kry van waar jou telefoon hom bevind. 

Sommige vervaardigers soos BlackBerry en Apple bied die afstanduitvee-funksie en opspoortoepassing vir hul nuutste toestelle, terwyl derdeparty toepassings beskikbaar is vir ander platforms.  

Laai veilige, goedgekeurde toepassings af

Die versoeking om gratis, nie-amptelike toepassings op jou iPhone of Android te probeer laai i.p.v. om dit te koop deur die iStore, is nou wel baie groot, maar jy neem `n groot risiko en stel jou foon bloot aan “malware”. Hou eerder by gemagtigde bronne wat streng kwaliteitskontrole toepas op die toepassings wat hulle verskaf en nie met nare ekstras kom nie.

Rugsteun jou data

`n Groot deel van jou lewe is op jou slimfoon – e-pos, telefoonkontakte, dokumente, fotos en baie meer. Net soos jy jou rekenaar (hopelik!) rugsteun, doen dieselfde met jou selfoon sodat alles nie verlore is as jou foon wegraak, gesteel word of beskadig word nie. Baie slimfone laat jou toe om `n deeglike rugsteun te maak na jou rekenaar of ten minste net die belangrikste data en opstellings aanlyn te stoor.
